Totally. All crypto concerns aside--though I am on the side of the fence that says, while Signal is clearly superior, MTProto still hasn't really been cracked, and WhatsApp's server-side key reset is a bigger deal--the UX for Telegram's mobile (iOS AND Android) and Desktop clients (Windows, Mac, AND Linux) all kick ass. They're blazing fast, sync works phenomenally (except for secure chats, RIP), the ability to share arbitrary files up to 1500 MBs is awesome, Instant View is everything FB Instant Articles should have been, and the (admittedly gray-area copyright) stickers ROCK.
My closest friends/family all use Telegram now because it's just better. When I want truly secure messaging, I use Signal or PGP
